Fabricated aerobic composting device

Abstract

The invention relates to a fabricated aerobic composting device. The device comprises five parts including a bin body, a fermentation center, aeration tiles, a functional film and a data acquisition and transmission system. According to composting requirements in different positions and at different time, the following working steps are required to be performed: constructing three surfaces of thebin body, reserving one surface as a material inlet, laying the aeration tiles and connecting the aeration tiles with the fermentation center; accomplishing a baffle of the reserved material inlet after material distribution, covering materials with the functional film, and fastening the periphery through wires and baffles; supplying gas to the materials through the fermentation center at the beginning of composting, and transmitting, recording and analyzing data by the data acquisition and transmission system, so as to control the composting speed; opening the film and then opening the baffleat the material inlet after composting is over, shoveling out all of the materials and the aeration tiles, sieving, separating the materials from the aeration tiles, finally dismounting the fermentation center and the bin body respectively and performing separate collection. The aerobic composting device is flexible, reliable, efficient, intelligent and economical.

Description

technical field [0001] The invention is an assembled aerobic composting device, which is mainly used for aerobic composting of organic solid waste in the environmental protection industry, can supplement large-scale composting processes, and can also meet the needs of small-scale composting. Background technique [0002] In the process of composting, it is first necessary to ensure that the material can be reduced to a certain moisture content, and secondly, the material must be fully in contact with the air, so that the microorganisms in the material can be fully aerobic and heat up rapidly. Membrane-covered composting is an improvement of static composting. Static composting has the characteristics of saving investment, adjustable processing scale, and flexible layout. At present, there are still a large number of static strip-stack composting systems in the United States, Canada and other places that are still in operation; and Germany, The United States and other Western...

Problems solved by technology

However, there are deficiencies in the above processes: (1) the static strip composting system occupies a large area, is greatly affected by the climate, and the secondary pollution is not easy to control; (2) static composting and film-covered composting cannot directly make the compost When reaching a certain height, concrete troughs need to be built, which not only increases the floor area, but also takes time and effort and is inconvenient to move; (4) The current process is not strong in the collection and transmission of material data, and the monitoring of the composting process is not timely enough.
